Not all critical applications live in a web browser. Your custom-built desktop software, internal tools, and other "thick client" applications are powerful assets, but they also represent a unique and often overlooked attack surface. Unlike web applications, these programs can store data locally, interact directly with the user's operating system, and communicate over proprietary network protocols. A vulnerability here can lead to a complete system compromise or a major data breach. Our Thick Client Assessment provides a deep-dive analysis to uncover these hidden flaws before an adversary can exploit them.
This assessment is essential for:
Software Development Teams building and maintaining custom desktop or enterprise applications.
Product Managers responsible for the security and integrity of a software product.
CISOs and Security Leaders who need to ensure all enterprise applications, not just web apps, are secure.
IT Teams deploying third-party thick client applications within the corporate environment.
Our assessment is designed to answer the critical questions about your application's security:
Can an unauthorized user bypass authentication or access other users' data?
Is sensitive information (like passwords or connection strings) stored insecurely on the user's computer?
Can the application's network traffic be intercepted or manipulated?
Could a flaw in the application allow an attacker to take control of the user's workstation?
Has the application been hardened against reverse engineering and tampering?
We analyze your thick client application from every angle, simulating the actions of a determined attacker. Our process is meticulous and tailored to the specific architecture of your software.
Application Reconnaissance: We begin by mapping the application's functionality, understanding its components, and identifying key areas of risk, such as user authentication, data handling, and communication channels.
Client-Side Analysis: We examine the application installed on the user's machine, searching for insecurely stored files, sensitive data in memory, and vulnerabilities in the application's binaries that could be exploited.
Network Traffic Interception: We analyze the communication between the client and its server, looking for unencrypted data, weak authentication, and opportunities to replay or manipulate traffic to gain unauthorized access.
Server-Side Testing: We probe the server-side APIs and infrastructure that support the application, testing for the same types of vulnerabilities found in traditional web applications.
Upon completion, you will receive a comprehensive security package that empowers your teams to act decisively:
Executive Summary Report: A high-level overview of the most critical risks and their potential business impact, designed for leadership and product owners.
Detailed Technical Findings Report: A complete guide for your developers, providing proof-of-concept for each vulnerability and clear, step-by-step instructions for remediation.
Confidential Debriefing Session: A secure meeting with our expert testers to discuss the findings in detail and assist your team in prioritizing remediation efforts.
